The Logical_type_id is a string that is a share type
identifier (repository id). The function returns true if the object
is an instance of that type or an ancestor of the "most derived"
type of that object.

The configuration context is used to override the global
SSL client side
configuration.

Note: Other ORB suppliers may not support this function completely
according to the OMG specification. Thus, a is_a call may
raise an exception or respond unpredictable if the Object is
located on a remote node.

This function can be used to test if the object has been destroyed.
It does this without invoking any application level code. The ORB
returns true if it knows that the object is destroyed otherwise
false.

The configuration context is used to override the global
SSL client side
configuration.

Note: The OMG have specified two different operators, _not_existent (CORBA version 2.0 and 2.2) and
_non_existent (CORBA version 2.3), to be used for this function. It is not mandatory to support
both versions. Thus, a non_existent call may raise an exception or respond unpredictable
if the Object is located on a remote node. Depending on which version, ORB:s you intend to
communicate with supports, you can either use this function or not_existent/1.

This function is used to determine if two object references are
equivalent so far the ORB easily can determine. It returns
true if the target object reference is equal to the
other object reference and false otherwise.
